UK Biodiversity Indicators 2019. Indicator C8 – Mammals of the wider countryside (bats) 2019
These documents support response indicator: C8. Mammals of the wider countryside (bats). The documents include a fiche, datasheet and technical background document.
This indicator shows changes in the relative abundance of 11 of the UK’s 17 breeding bat species, based on data from transect surveys, roost counts and counts at hibernation sites. Whilst 11 species are included there are 10 species trends, as an aggregate trend is used for the whiskered bat (Myotis mystacinus) and Brandt’s bat (Myotis brandtii); these 2 species are difficult to distinguish in the field. Bat species make up a third of the UK’s mammal fauna and occur in most lowland habitats across the UK.

The UK indicators were comprehensively reviewed during 2011 and 2012 to ensure they continued to be based on the most robust and reliable available data; and remained relevant to the new international goals and targets. Since then the indicators have been refined to improve their relevance/quality, and new indicators developed to fill gaps. In this version of the publication as many as possible of the indicators have been updated with new data. In some cases, however, development work is ongoing, and where this is the case, the work to develop them has been described briefly.
